KRD DC109

By kwong on Jan 28, 2018

6 268 3

This frame was my early design, inspired by a few other frames on the market with my own twist - Dead Cat style.

Only one was made for testing, originally designed for AIO micro camera, recently I modified the design to accommodate separate camera/VTX to allow higher camera tilt angle (20, then 30 degree) in the very limited space.

Performace was underwhelming until I discovered Gemfan 2540 props, thus the high tilt (for a micro).

I've made the design files available on Thingiverse, if you're interested you can grab them and make your own, or purchase the carbon plates from the link below (you will still need 3D printed parts and hardware though).

Since 2.5" mciros are so much fun I'm designing updated versions for use with 19mm micro cameras, also slightly bigger one for Split Mini (because micro HD footage obsession lol), stay tuned.

Looks awesome! I'm also super interested in a 2-3" and getting HD footage. Did you have a shop cut your frame design? Expensive?

Thanks

Split mini on 2.5" is still on conceptual phase, squeezing 4-5 boards in a micro is difficult and I hate thick quads, low profile FTW!
Before that I think I would go design a updated 2.5" to accommodate 19mm micro cam, then on top of that develop a Split Mini variant.

I used to order custom cut CF from China but now I use Armattan Productions, cost is very reasonable and same Armattan quality, only downside is the design approval wait period plus production lead time.

BTW, 3" HD is here: https://rotorbuilds.com/build/8891 (a big one though)

Build a 5" Long Range Drone - Transformer Ultralight

Jun 21, 2021

AirbladeUAV has done it again and this time they've brought long range to the 5" class! Based on the popular Transformer Mini, the new Transformer 5" Ultralight adopts a lot of the same design philosophies with larger props and more payload capacity. It can fly upwards of 20 minutes on a 4 cell Li-Ion battery pack and in ideal conditions it's got a range of over 4 to 5 miles. In this guide I'll walk..

Build a DJI FPV Cinewhoop - QAV-CINE Freybott Edition

Mar 04, 2021

With the release of the DJI FPV Drone cinematic FPV has become a lot more accessible, but you certainly don't want to crash a $750 drone! The QAV-CINE Freybott is a compact, lightweight cinematic FPV drone that can take a hit and keep going. It's a lot safer to fly indoors and around people. With a naked GoPro or the SMO 4k you can capture some great stabilized footage. In this guide I'll show you..
